Anything, That is, it's too late to take a tumble.

虽然恍然大悟，但为时晚矣！

The results of this study indicate that changing the angle of the intake port has a profound effect on the flow field during the intake stroke of the engine cycle. For the case with the intake-exhaust valves canted at zero degree (the so-called vertical valves), the tumble ratio, swirl ratio, turbulent intensity, and turbulent kinetic energy in the direction perpendicular to the bisecting plane of the cylinder are at their highest levels than those obtained for the other cases. This effect is most pronounced after the compression stroke of the cycle. As a result of this study, it is observed that the behavior of the overall flow field from the intake to the completion of compression stroke has a major impact on the effectiveness of the mixing of fuel-air prior to the ignition of the engine cycle.

结果显示，改变进排气阀的倾斜角度对进气期间的流场变化有很明显的影响，其中以垂直阀(进排气阀倾斜0度)所得的 Y轴向(Y方向系垂直於将汽缸对分为二平面的方向)滚流强度、涡漩比、紊流强度、紊流动能等流场强度为最强；若以流体经活塞压缩后的流场特性进行探讨，所得结果显示压缩冲程对汽缸内流场的效应是不容忽视的；因此由进气到压缩过程结束的整体流场现象，才是影响引擎点火前的油气混合程度与燃烧品质的关键。

When you're not wearing your jewellery, be careful that pieces do not tumble against each other to avoid scratching or dulling.

当你不穿你的珠宝这件不小心跌倒，以避免对对方抓痒或壮志。

Shooting mechanics are sharp and allow you to easily utilize your arsenal to slaughter your monstrous foes, and for every time that a creature keels over lamely from a killer revolver bullet, there will be two others that whip back from the impact of a headshot or tumble away from a satisfying shotgun blast.

射击力学是雪亮的，让您可以轻松地利用你的武器库，你的骇人听闻的屠杀敌人，并每次1败下阵来生物龙骨从杀手左轮手枪子弹结束，将有两个人的鞭子回来的爆头或下跌的影响远离爆炸满意的猎枪。

In their zeal to protect the torch during a rough and tumble transit through London last month, they apparently manhandled Lord Sebastian Coe, the chairman of London's Olympic organising committee.

在上个月粗野而混乱的火炬伦敦传递中，他们很明显的粗暴对待了Sebastian Coe爵士，伦敦奥委会主席。

In their zeal to protect the torch during a rough and tumble transit through London last month, they apparently manhandled Lord Sebastian Coe, the chairman of London's Olympic organising committee.

个月火炬在伦敦的艰难蹒跚的传递中，由于他们的热情保护而明显粗暴地推搡了伦敦奥运筹办委员会主席科尔勋爵。

Many companies are mothballing mines and curtailing exploration to conserve cash as prices tumble.

由于价格暴跌，许多公司封存矿山、减少勘探以保存现金。

Many companies are mothballing mines and curtailing exploration to conserve cash as prices tumble.

卢西尔向英国《金融时报》表示，勘探将受到影响，尤其是在刚果民主共和国。

In 1990s, the departments of education at the federal level and the state level came to see eye to eye in that the miscellaneous curricula in senior' high schools must be neatened, and rough-and-tumble standards for curricula must be standardized.

进入20世纪90年代以来，美国联邦教育部和绝大多数州都一致认为：全美高中庞杂的课程设置必须整肃，混乱的课程标准必须规范，全国性的核心课程基准和各州基于全国基准的本州课程标准的出台势在必行；同时，只有更严格的学业标准和更高的期望值才能使学生达到更高的学业成就。

Research Centre for Buffettism matter how intelligently run. Finally, the market's major fear of the moment is that West Coast real estate values will tumble because of overbuilding and deliver huge losses to banks that have financed the expansion. Because it is a leading real estate lender, Wells Fargo is thought to be particularly vulnerable. None of these eventualities can be ruled out. The probability of the first two occurring, however, is low and even a meaningful drop in real estate values is unlikely to cause major problems for well-managed institutions. Consider some mathematics: Wells Fargo currently earns well over $1 billion pre-tax annually after expensing more than $300 million for loan losses.

以上所提到的风险都很难加以排除，当然第一点与第二点的可能性相当低，而且即使是房地产大幅的下跌，对于经营绩效良好的银行也不致造成太大的问题，我们可以简单地算一下， Wells Fargo 现在一年在提列 3 亿美元的损失准备之后，税前还可以赚 10 亿美元以上，今天假若该银行所有的 480 亿借款中有 10%在 1991 年发生问题，且估计其中有 30%的本金将收不回来，必须全部转为损失，则在这种情况下，这家银行还是可以损益两平。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
